I suggest you update your ip to whatever you currently get for api.wunderground.com They probably just switched servers around.

Thank you for the response. I tried that and I get the same symptoms. Pinging api.wundeground.com currently gives me 23.46.166.236 and using that IP also fails.
Why can't this system simply be pointed to wundergrounds url? Is that planned as an enhancement?
Doing a DNS lookup in C is unnecessarily complicated. No one has had time.

I've been using 38.102.136.138 for years without issue. The problem is api.wunderground.com resolves in round robin to many IP addresses. Some of those addresses go away occasionally.

I respectfully disagree that the problem is an IP address resolution issue. I have taken the IP that responds to the ping at api.wunderground.com and inserted it into the json request url documented in the api documentation and I get a valid response in the browser. I them put that IP in the program and get "Invalid response" in sprinkler_pi.
e.g. If I put 38.102.136.138 in the program and check it will fail. If enter the same IP in this URL from the api documentation and it works. http://38.102.136.138/api/214745275e67dafb/conditions/q/pws:KVAVIRGI39.json
Therefore the problem is NOT the IP address but it is either the request or parsing the response. Looking at my wunderground analytics page does not show many requests so I am assuming for now that it is the request going out to the api that is the problem.

getaddrinfo() http://www.beej.us/guide/bgnet/output/html/singlepage/bgnet.html#getaddrinfo
I just got my Pi connected to wunderground. nslookup api.wunderground.com = 104.73.96.110. Make sure you typed your personal API key correctly.
I think this issue is related to the Akamai dns servers. If I test the request in the browser it works with the DNS name, but does not with the IP. I think Akamai is inspecting the host name sent across the wire and only accepts host names not IP's. I will look at the code and see if its something I can contribute.
This is the error I get when using IP. "The requested URL "[no URL]", is invalid."
I also verified it doesn't work in postman with setting Host header.
Ideally it would make a proper http request to api.wunderground.com but it's complicated to do that in C code. A compromise might be just adding a header for Host: api.wunderground.com which should satisfy akamai.

I tried that through postman, but it still gave the same error. Its weird to say the least.
It's possible that the ip you have is no longer assigned to wunderground... are you using a fresh ip from dig or ping api.wunderground.com?

Ok so using the IP. Its weird it works when I use the ZIP in the sprinklers_pi UI, but not the PWS.
Strange because I use pws... I'll check which ip later.

I get the same behavior, using the zip code, I get weather data. When I enter the PWS, I get nothing and the diagnostics fail with error "Invalid Response from WUnderground server!".
I am using pws with 172.224.165.103

I too am having the error but what i see is that the API Key is 32 long and the app only uses 16 am i missing something here?
Both of my keys, one which I just generated are 16 characters. Please double check your key settings on http://api.wunderground.com/weather/api Generate (Purchase for $0) a Developer level "Anvil Plan" key.

Some how i got to the OpenWeathermap api key and it is 32 you are so right my bad thanks But it is still giving the errror :(
Does the pws you have selected work when you use the test page in the api docs?

172.224.165.103 still error
Hello. When I had the same issue with the PWS I dug into the code a little. From my investigation it seemed to be an issue with weatherundergrounds CDN. They don't seem to like the web request for some reason.
So I was looking at the spec for HTTP GET(https://www.w3.org/Protocols/rfc2616/rfc2616-sec5.html) specifically section 5.1.2.And this part in particular "The absoluteURI form is REQUIRED when the request is being made to a proxy." Maybe we should change the GET to send across the full uri instead of just the host? I can test this out tonight if noone else can.
Again I'm not criticizing the code. Just suggesting possible fix.
See my pull request, that should resolve IP resolution and proxy issues.
A system that was working has recently started to get errors, "Invalid Response from WUnderground server!" when running diagnostic. Using a PWS and the settings page is configured with the IP 104.72.15.199. api.wunderground.com does not resolve to that IP but then it has not from the first time I have installed the program tail /var/log/sprinklers_pi after running diagnostic shows the entry: Bad Wunderground Response.
